Here is a program that will allow you to input a message and have it print the message as a banner on the out 2040 printer.
The letters are generated one at a time by PEEKing at the letter to be generated in the ROM, making it 8 times normal size and turning it on it’s side and then COPYing it to the printer.
The program is much faster faster in FAST mode, but you can’t see the letter forming. By changing line 128, you can change the character that is actually used in printing the large one.
Enter the program as listed listed and use GOTO 280 to SAVE it so that it will self start next time it’s LOAded.
